Clamp Assisted Reduction of the Transverse Acetabular Fracture with Anterior Column Screw Fixation and Posterior Plating

Displaced transverse acetabular fractures are unstable injuries that frequently require repair. Although multiple approaches, techniques, and fixation constructs have been described to treat this pattern, achieving an anatomical reduction and applying fixation to maintain this until union remains the goal of treatment. We present a surgical technique for transverse or transverse/posterior wall acetabular fractures repaired using a clamp-assisted reduction through the sciatic notch, followed by anterior column screw fixation and subsequent posterior column plating through a Kocher-Langenbeck exposure. We review a case series of 55 patients treated with this technique and evaluate reduction quality using postoperative computed tomogram scans to assess for any residual step-off.
